After reaching an important support level, Teekay Tankers (TNK Quick QuoteTNK - Free Report) could be a good stock pick from a technical perspective. TNK surpassed resistance at the 20-day moving average, suggesting a short-term bullish trend.

The 20-day simple moving average is a popular trading tool. It provides a look back at a stock's price over a 20-day period, and is beneficial to short-term traders since it smooths out price fluctuations and provides more trend reversal signals than longer-term moving averages.

Like other SMAs, if a stock's price is moving above the 20-day, the trend is considered positive. When the price falls below the moving average, it can signal a downward trend.

TNK has rallied 14% over the past four weeks, and the company is a Zacks Rank #2 (Buy) at the moment. This combination suggests TNK could be on the verge of another move higher.

Once investors consider TNK's positive earnings estimate revisions, the bullish case only solidifies. No earnings estimate has been lowered in the past two months, compared to 1 raised estimates, for the current fiscal year, and the consensus estimate has increased as well.

With a winning combination of earnings estimate revisions and hitting a key technical level, investors should keep their eye on TNK for more gains in the near future.
